The placing grooves 71 are both communicated with the limiting grooves.

The opposite ends of the cross bars 73 are fixedly installed with sliding blocks 74. The sliding blocks 74 are respectively slidably connected to the rear sides of the inner cavities of the adjacent placing grooves 71. Plug blocks 75 are fixedly installed on the opposite sides of the sliding blocks 74. Slots are opened on both sides of the limiting block 9, and the plug blocks 75 are respectively movably inserted into the inner cavities of the adjacent slots. By pulling the handle 736, the adjacent sliding blocks 74 can be slid in the inner cavities of the adjacent placing grooves 71 through the adjacent cross bars 73. And under the action of the sleeve rod 732, the first rack plate 733 and the rotating gear 735, the second rack plate 734 can be moved to one side, and then the adjacent sliding blocks 74 can be slid in the inner cavities of the placing grooves 71, so that the two plug blocks 75 can be far away from the inner cavities of the adjacent slots to facilitate the replacement of the upper die 5, and the effect of subsequent sheet metal bending processing can be improved.

[0027] A handle 736 is fixedly installed at the end of the cross bar 73 on the other side. Spring sleeves 731 are movably sleeved on the outer peripheries of the cross bars 73 near the opposite ends, and the two ends of the spring sleeves 731 are respectively fixedly connected to the adjacent sliding blocks 74 and the adjacent fixing plates 72. Sleeve rods 732 are fixedly sleeved on the outer peripheries of the cross bars 73 near the middle position. First rectangular openings are opened at the rear sides of the placing grooves 71 near the middle position.

The rear ends of the sleeve rods 732 are respectively fixedly connected with a first rack plate 733 and a second rack plate 734. A rotating gear 735 is jointly meshed on the opposite sides of the second rack plate 734 and the first rack plate 733 near the other side.

[0028] A vertical rod 7351 is fixedly installed at the bottom of the rotating gear 735, and the bottom end of the vertical rod 7351 is rotatably connected to the bottom of the inner cavity of the second rectangular opening.

[0029] A groove 61 is opened at the middle position on the top of the workbench 1. An electromagnet 62 is fixedly installed at the bottom of the inner cavity of the groove 61. The electromagnet 62 is magnetically attracted to the lower die 6. By arranging the electromagnet 62, it is convenient to install and disassemble the lower die 6.

[0030] Embodiment 2: This embodiment is an improvement made on the basis of Embodiment 1. Specifically, please refer to Figure 1 and Figure 2, the impurity removal component 8 includes an airbag 81 fixedly installed near one side of the top of the connection block 4 and a hose 82 inserted near the bottom of the rear side of the airbag 81. The bottom end of the hose 82 is fixedly installed with a blowing head 83, and the bottom of the blowing head 83 is fixedly installed with a support frame 84, and the support frame 84 is fixedly connected to the L-shaped plate 2. When the connection block 4 moves upward, the airbag 81 is squeezed, and the gas enters the inner cavity of the blowing head 83 through the hose 82, so as to be able to blow away the debris in the inner cavity of the lower die 6, avoid the debris adhering to the sheet material during the next bending, and improve the use effect of the device.

[0031] An air inlet pipe is inserted near the top of one side of the airbag 81, and an air inlet check valve is arranged on the air inlet pipe. An exhaust check valve is arranged near the front end of the outer periphery of the hose 82.

[0032] Working principle: When the utility model is in use, the staff places the sheet material on the top of the lower die 6. At this time, by starting the hydraulic rod 3, the connection block 4 fixed on the hydraulic rod 3 moves downward, and the upper die 5 installed on the connection block 4 bends the sheet material. When the connection block 4 moves downward, the airbag 81 can be stretched, and air is introduced into its interior through the air inlet pipe. When the connection block 4 moves upward, due to the setting of the hose 82, the gas in the airbag 81 is squeezed out. Through the setting of the blowing head 83, the debris generated during the bending process in the inner cavity of the lower die 6 is blown away, avoiding the debris adhering to the sheet material during the next bending, and improving the use effect of the device. When it is necessary to replace the lower die 6 or the upper die 5, at this time, by turning off the external power supply of the electromagnet 62, the lower die 6 can be directly removed. When it is necessary to disassemble the upper die 5, at this time, by pulling the handle 736, the cross bar 73 fixed on the handle 736 can make the sliding block 74 slide in the inner cavity of the placement groove 71, and the insertion block 75 fixed on the adjacent sliding block 74 can be far away from the inner cavity of the adjacent slot. When the cross bar 73 moves to one side, under the connection of the sleeve rod 732, the first rack plate 733 can move to the other side, so that the rotating gear 735 rotates, and then the second rack plate 734 can move to one side. Under the connection of the adjacent cross bars 73 and the cooperation of the adjacent cross bars 73 and the sliding blocks 74, the adjacent insertion blocks 75 can be far away from the inner cavity of the adjacent slots, which is convenient for the staff to replace the upper die 5 and improve the subsequent bending processing effect of the sheet material.
